Worst case - James Patterson

The son of one of New York's wealthiest families is snatched off the street and held hostage.
But this kidnapper isn't demanding money: he quizzes his prisoner's family on the price others pay for his life of luxury - wrong answers are fatal.
Detective Michael Bennett leads the investigation, and as another student disappears, powerful, well-connected families pressurise all possible agencies to stop this killer.
Eventually, the FBI sends their top Abduction Specialist, Agent Emily Parker.
Bennett's work life - and love life - suddenly get more complicated.
And Bennett is unable to protest against the FBI's intrusion on his case, when, suddenly, the mastermind changes his routine.
His plan involves the most shocking demonstration yet - one that could bring cataclysmic devastation to every inch of New York.
